Is the Tendency to Engage in Entrepreneurship Genetic?
利用英国870对同卵双胞胎和857对异卵双胞胎数据，通过定量遗传学方法分析创业倾向的遗传与环境影响，发现遗传因素作用显著，家庭环境影响很小。
We used quantitative genetics techniques to compare the entrepreneurial activity of 870 pairs of monozygotic (MZ) and 857 pairs of same-sex dizygotic (DZ) twins from the United Kingdom. We ran model-fitting analyses to estimate the genetic, shared environmental and nonshared environmental effects on the propensity of people to become entrepreneurs. We found relatively high heritabilities for entrepreneurship across different operationalizations of the phenomenon, with little effect of family environment and upbringing. Our findings suggest the importance of considering genetic factors in explanations for why people engage in entrepreneurial activity.
